High GPU usage in HourOfCode

Hi, i just finished the beginners tutorial “Hour of Code” from here: Lesson Plans - Unreal Engine

Now i packaged up the game and tried to play it but had to wonder the GPU usage was very high, about 86% GPU load. Is this normal for the game or are there tricks and tipps to make the performance significantly better and where I can find them?

Thank you in advance for your response.
